You will need to know how big a 5cm image is a 600 dpi.

600 pixels per inch at roughly 2.56 cm per inch times 5 cm
   => 600 / 2.56 * 5  => 1172 pixels  wide...

You will need to have a big enough initial density when reading to
produce at least 1200 pixel wide image (first -density)

  convert -density 600x600 pic1.pdf -resize 1172x \
          -density 600x600 pic.png
